We divide 870531 by 8
We want to divide 870531 by 8.

Advancing to step 1:
The number 8 fits into 8 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 8

On to step 2:
The number 8 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 8

Going ahead to step 3:
8 goes into 70 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 64 from 70 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 8

Step 4:
8 goes into 65 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1088.0
Subtracting 64 from 65 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 8

Let's proceed to step 5:
8 goes into 13 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 10881.0
Subtract 8 from 13 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 8

Advancing to step 6:
If we divide 51 by 8, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 108816.0
If we subtract 48 from 51, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 8, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 108816.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 108816.37
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
8 goes into 40 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 108816.375
Subtract 40 from 40 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 108816.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 108816.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 108816.375 with a balance of 0.0.
